You can already drag files/folders into the detailed information (or preview) window.
Set up your renaming parameters in the custom renaming list of the main window, then either press the scan button or select 'View' from the top menu and then select 'Detailed Information...'. That should raise the detailed info window; It is in here that you can drag names.

As for exclusions, there are lots of filters available. Just press the 'More' button on the main window.
